Ed (Jay Mohr) and Alice (Julianne Nicholson) are on the verge of getting married when she realizes that she wishes she'd had a more active love life while still single. The couple mutually decide to have an open relationship in the months before their wedding, and initially this seems to improve their connection, particularly in the bedroom. However, as Ed and Alice get more involved in their own flings, the experiment goes awry, resulting in emotional turmoil for both of them. Wikipedia
